Introduction
The Ubuntu developers are moving quickly to bring you the latest and greatest software the Open Source community has to offer. This is the second Ubuntu 10.04 beta release, which brings a host of exciting new features.
Note: This is a beta release. Do not install it on production machines. The final stable version will be released on April 29, 2010.
Upgrading from Ubuntu 9.10 or Ubuntu 8.04 LTS
To upgrade from Ubuntu 9.10 on a desktop system, press Alt F2 and type in "update-manager -d" (without the quotes) into the command box. Update Manager should open up and tell you: New distribution release '10.04' is available. Click Upgrade and follow the on-screen instructions.
To upgrade from Ubuntu 9.10 on a server system: install the update-manager-core package if it is not already installed; edit /etc/update-manager/release-upgrades and set Prompt=normal; launch the upgrade tool with the command sudo do-release-upgrade -d; and follow the on-screen instructions.
To upgrade from Ubuntu 8.04 LTS: follow the same instructions as for the appropriate Ubuntu 9.10 upgrade, but set Prompt=lts instead of Prompt=normal.
